Based on Geant4 modeling, we simulated the underwater erenkov light field in open seawater and coastal seawater, which was excited by different kinds of gamma-rays. The gamma-rays were originally released by fission products and activation products in the reactor coolant. The physical characteristics of the underwater erenkov light field were mathematically analyzed, including the spatial distribution principle, the correlation between the energy density and elevation angle, the energy density functions of erenkov photons, and the erenkov photon spectrum. Compared with other published research results, it was proved that the erenkov photons are in the range of 200-810 nm in both seawater types, but the peak wavelength in these seawater types is 420 nm (open seawater) and 570 nm (coastal seawater), and the strong absorption and scattering of suspended particles caused large attenuation in the ultraviolet range and infrared range. erenkov photons were symmetrically distributed along the emitting direction of gamma-rays, and the maximum energy density of erenkov photons appeared at the center of the emission direction of gamma-rays. The erenkov halo might only be observed in clear open seawater. The research results also show us that in the following field experiment, to collect the erenkov photons in water, deploying underwater photo-electric detection devices outside the reactor compartment of the floating nuclear power plants would be an effective way to locate the suspected coolant leakage position and leakage rate.
